Strap for Montbrillant 01 Red Gold / Diamondworks / Aurora Blue / Croco

The lug width of the Breitling Montbrillant RB0130AL|C896|718P is 20 mm. This measurement is taken with a digital calliper between the two lugs, at the precise point where the spring bar sits, and determines all strap compatibility for this reference.

For an 18-carat red gold case such as that of the Montbrillant, vegetable-tanned alligator leather with a gloss finish is the most aesthetically coherent choice. The regular grain of the alligator belly complements the polished surfaces of the gold without overwhelming them. Alternatively, box-calf leather and shell cordovan offer more understated yet equally refined options.

To replace the strap on a Breitling Montbrillant, you will need a spring bar tool. Insert the forked tip between the strap and the lug, apply gentle pressure to release the spring bar, then slide the strap free. Take care not to scratch the red gold case: it is advisable to protect the lugs with masking tape before proceeding.

Yes. Any strap with a 20 mm attachment is technically compatible. To ensure the correct fit and visual continuity with the red gold case, it is recommended to choose straps with shaped ends that follow the profile of the Montbrillant's lugs. Handcrafted 20 mm straps tailored to this case profile are available at milanostraps.it.

The lifespan of a leather strap depends on the material and care taken. A quality vegetable-tanned alligator strap, with daily wear and regular conditioning, typically lasts between 3 and 5 years before replacement becomes necessary. Shell cordovan tends to last longer due to the density of its fibre. Box-calf straps have an average lifespan of 2 to 3 years with intensive use.
